A roaming device sends, through a visited network and a proxy network, to a home network, an identifier for a first subscription. The home network sends, through the proxy network, to the visited network, data relating to the first subscription. The proxy network sends to the home network a first temporary address. The visited network sends to the proxy network a second temporary address. The device activates a second subscription. The device sends, through the visited network and the proxy network, to the roaming provider network, an identifier for the second subscription. The roaming provider network sends, through the proxy network, to the visited network, data relating to the second subscription. The proxy network registers the first subscription identifier, the second subscription identifier, the first temporary address and the second temporary address. The proxy network sends to the roaming provider network the first temporary address.

A method of using subscriber identification information stored in mobile user equipment (UE) to connect to a communication service over a public wireless network in the UE, establishing a communication link between the UE and a device, generating network access information (NAI) associated with the communication service in the UE, and sending the NAI from the UE to the device via the communication link. The method further comprises connecting the communication service in the device using the NAI and terminating the connection of the communication service in the UE.

A method for signalling congestion avoidance based on Non-Access Stratum (NAS) level congestion control in a mobile network includes activating or starting a group specific NAS level congestion control mechanism that applies to a group of terminals; receiving at a serving node of a terminal of the group of terminals an NAS Session Management (SM) request message from the terminal related to a particular access point name (APN); and transmitting from the serving node of the terminal to the terminal one or more NAS reject messages that indicate suppression or prevention of NAS SM signalling of the terminal that is related either to all APNs to which the terminal has established or activated IP bearers or to all APNs to which the terminal has a subscription.

Provided is a method for saving a standard format page. The method includes: generating a standard format page which includes a first filling entry, the first filling entry having a default filling value and being configured to be filled with a PLMN identity of a visited place; transmitting the standard format page to the first mobile terminal located at the visited place; receiving a first standard format page transmitted by the first mobile terminal, the first standard format page being a standard format page in which the first filling entry has been filled with the filling value; and identifying and saving the first standard format page. The present disclosure further provides a server for saving a standard format page.

Techniques for providing reminders based on social interactions between users of electronic devices are described. Social reminders can be set to trigger based on social interactions of users. For example, a user may request to be reminded to discuss a certain discussion topic with a particular phonebook contact, when the user next encounters the contact.

The present invention provides a data update method, an apparatus, and an eUICC. The method is applied to an eUICC in which a management apparatus and at least one SE are disposed, where the at least one SE is configured to store an application corresponding to at least one profile. The management apparatus receives a profile enabling request, where the enabling request is used to switch a source profile to a target profile, the enabling request includes identifier information of the target profile, and the source profile is a profile that is in an enabled state before the switching; and updates a first correspondence to a second correspondence according to the enabling request; and the second correspondence is a correspondence between a second application set and the target profile, and the second application set includes at least one application in the first application set.

The present disclosure relates to a system and method for providing seamless service to a dual SIM enabled user equipment. The seamless service is provided by smoothening the broadcast services which is based on the dual SIM mobile devices with a single radio frequency chain that will require tune-away from one a one type of radio service to another type of radio service when checking for possible incoming calls. Due to the tune away user experience service lag in terms of lag in the video playback which is estimated by the present system and method to perform an appropriate smoothing operation for a disruption free user experience in ailing service.
